CVE-2025-31976Network attack vector

Credential exposure via transient backend communication

Published May 6, 2026 · Updated May 6, 2026

Credential exposure in HCL BigFix Service Management 23 allows remote attackers to obtain credentials during internal backend communication. HCL states that the application leaves credentials insufficiently protected briefly while exchanging them with an internal backend, but does not identify the protocol, endpoint, or protection failure. No privileges or user interaction are required; successful access depends on capturing the transient credential material and enables its misuse, with no reported availability impact.
